Ukunyuswa kwebhodi ye-AS5510 Adapter

I-AS5510-AB inokulungiswa kwinkqubo ekhoyo yomatshini ngemingxunya yayo emine yokunyuka. Imagnethi yepali ezi-2 ezilula ezibekwe ngaphezulu okanye phantsi kwe-IC zingasetyenziswa.
Umfanekiso 4:
Ukufakwa kwebhodi yeadaptha ye-AS5510 kunye nobukhulu

Ubuninzi bohambo oluthe tye ampukukhanya kuxhomekeke kwimilo yemagnethi kunye nobukhulu kunye namandla kazibuthe (isixhobo semagnethi kunye ne-airgap).
Ukuze ulinganise intshukumo yomatshini kunye nempendulo yomgca, imilo yemagnethi kwi-airgap esisigxina kufuneka ifane ne-Figure 5:.
Ububanzi boluhlu lomgca wommandla wemagnethi phakathi kweepali zaseMantla nezisezantsi zimisela obona bungakanani bobungakanani bokuhamba bemagnethi. Ubuncinane (-Bmax) kunye nobukhulu (+Bmax) amaxabiso omagnethi kuluhlu lwelayini kufuneka abe ngaphantsi okanye alingane nenye yeemvakalelo ezine ezikhoyo kwi-AS5510 (register 0Bh): Uvakalelo = ± 50mT, ± 25mT, ±18.5mT , ±12.5mT Irejista yemveliso ye-10-bit D[9..0] ISIPHUMO = Indawo (mT) * (511/Uvakalelo) + 511.

Le yeyona meko ifanelekileyo: uluhlu lomgca wemagnethi yi-±25mT, ehambelana ne-±25mT yokuseta uvakalelo lwe-AS5510. Isisombululo sokufuduswa vs. ixabiso lemveliso ligqwesileyo.
Max. Umgama wokuHamba TDmax = ±1mm ( Xmax = 1mm)
Uvakalelo = ±25mT (Bhalisa 0Bh ← 01h)
Bmax = 25mT
→ X = -1mm (= -Xmax) Indawo (mT) = -25mT ISIPHUMO = 0
→X = 0mm Ummandla (mT) = 0mT ISIPHUMO = 511
→ X = +1mm (= +Xmax)
Ummandla (mT) = +25mT ISIPHUMO = 1023
Uluhlu oluguquguqukayo lwe-OUTPUT ngaphezulu kwe-±1mm: DELTA = 1023 – 0 = 1023 LSB
Isisombululo = TDmax / DELTA = 2mm / 1024 = 1.95µm/LSB
Exampn 2:
Ukusebenzisa useto olufanayo kwi-AS5510, uluhlu oluyilayini lwemagnethi ngaphezu kokufuduswa okufanayo kwe-±1mm ngoku yi-±20mT endaweni ye-±25mT ngenxa ye-airgap ephezulu okanye imagnethi ebuthathaka. Kuloo meko isisombululo sokufuduswa vs. ixabiso lemveliso lisezantsi. Max. Umgama wokuHamba TDmax = ±1mm (Xmax = 1mm): Uvakalelo olungatshintshanga = ±25mT (Bhalisa 0Bh ← 01h): alutshintshanga
Bmax = 20mT
→ X = -1mm (= -Xmax)
Ummandla (mT) = -20mT ISIPHUMO = 102
→ X = 0mm Ummandla (mT) = 0mT ISIPHUMO = 511
→ X = +1mm (= +Xmax)
Ummandla (mT) = +20mT OUTPUT = 920;
Uluhlu oluguquguqukayo lwe-OUTPUT ngaphezulu kwe-±1mm: DELTA = 920 – 102 = 818 LSB
Isisombululo = TDmax / DELTA = 2mm / 818 = 2.44µm/LSB
Ukuze ugcine esona sisombululo silungileyo senkqubo, kuyacetyiswa ukuba ulungelelanise uvakalelo ngokusondeleyo njengeBmax yemagnethi, kunye neBmax <Ubuntununtunu ukuphepha ukugcwala kwexabiso lemveliso.
Ukuba isibambi semagnethi sisetyenzisiwe, kufuneka senziwe ngento engeyiyo i-ferromagnetic ukuze kugcinwe amandla omhlaba wemagnethi aphezulu kunye nokulandelelana okuphezulu. Izinto ezinjengobhedu, ubhedu, i-aluminiyam, intsimbi engatyiwayo zezona zikhetho zilungileyo ukwenza le nxalenye.

Ukuqhagamshela i-AS5510-AB

Iingcingo ezimbini (I²C) zifuneka kuphela kunxibelelwano ne-MCU yomkhosi. Ukutsalwa kwe-resistors kuyadingeka kwi-SCL kunye nomgca we-SDA. Ixabiso lixhomekeke kubude beengcingo, kunye nesixa samakhoboka akumgca we-I²C ofanayo.
Ukunikezelwa kwamandla okuhambisa phakathi kwe-2.7V ~ 3.6V ixhunyiwe kwibhodi ye-adapter kunye ne-resistors yokutsala.
I-adapterboard yesibini ye-AS5510 (ukhetho) inokudityaniswa kumgca ofanayo. Xa kunjalo, idilesi ye-I²C kufuneka itshintshwe ngokuvala iJP1 ngocingo.

Isoftware example

Emva kokunika amandla inkqubo, ulibaziseko lwe>1.5ms kufuneka lwenziwe phambi kwe-I²C yokuqala
Funda/Bhala umyalelo nge-AS5510.
Ukuqaliswa emva kokunyuswa kombane kuyakhethwa. Ibandakanya:
-Ulungelelwaniso lobuthathaka (Bhalisa 0Bh)

Imagnethi polarity (Bhalisa 02h bit 1)

Imowudi ecothayo okanye ekhawulezayo (Bhalisa 02h bit 3)
Imowudi yokuPhawula amandla (Bhalisa 02h bit 0)

Ukufunda ixabiso lemagnethi liqonde phambili. Le khowudi yomthombo ilandelayo ifunda ixabiso le-10-bit le-magnetic field, kwaye liguqulela kumandla wemagnethi kwi-mT (millitesla).
Example: Uvakalelo luqwalaselwe kuluhlu + -50mT (97.66mT/LSB); I-Polarity = 0; useto oluhlala lukhona:

I-D9..0 ixabiso = i-0 ithetha -50mT kwinzwa yeholo.

I-D9..0 ixabiso = i-511 ithetha i-0mT kwi-sensor yeholo (akukho ndawo yamagnetic, okanye akukho magnethi).
I-D9..0 ixabiso = i-1023 ithetha + i-50mT kwinzwa yeholo.
